i need to prototype a system that transforms audio (i.e. of a person singing) into a singing stadium effect. i've tried few vocoder examples with white noise and then stadium sound fed as carrier signal. it sounds warm but not so realistic. hope someone can put me into right direction. all comments and suggestions are welcome.

reverb or is that too simple?

I always prefer simple solutions. I will some reverb to the patch and see what happens. Thank you!

make sure you mix in some of the dry signal with the effected version too. that was my mistake for a while. i was just feeding it through reverb and not adding any of the original. obviously sounded awful.
